What this calculator includes
- Live net-income-to-EBITDA reconciliation with signed income-tax benefits.
- Optional net-revenue denominator and clearly defined EBITDA margin.
- Separate Adjusted EBITDA with up to 12 uniquely described signed items.
- Negative results and missing or zero denominators kept explicit.
- Private in-tab inputs, currency labels without conversion and print-friendly results.
How to calculate EBITDA from your records
- Select one reporting period and one entity perimeter. Replace all fictional example amounts with matching income-statement records.
- Enter net income after interest and income taxes. Find the included interest, income-tax expense or benefit, depreciation and amortization; enter zero explicitly when absent.
- Enter matched net revenue only when you need a margin. Blank revenue keeps the earnings total but does not invent a denominator.
- Review the signed bridge. Open Adjusted EBITDA only for documented extra adjustments; keep the base subtotal visible.
- Reconcile the earnings result with cash flow and commitments before using it for a business decision.
EBITDA formula and margin denominator
EBITDA = net income + included interest expense + income-tax expense + included depreciation + included amortization. EBITDA margin = EBITDA ÷ positive net revenue × 100. A negative income-tax benefit reduces the add-back bridge.
EBIT plus depreciation and amortization can be another route only when EBIT is correctly defined and reconciled. Operating profit does not always equal EBIT when non-operating items exist. Do not start with EBITDA and add D&A again.
Identify the right income-statement inputs
| Input | Use | Do not substitute |
|---|---|---|
| Net income | Bottom-line earnings for the chosen period | Revenue or bank balance |
| Interest | Included interest expense under the stated definition | Loan principal or entire loan payment |
| Income tax | Included income-tax expense or signed benefit | Every sales/payroll tax or cash payment |
| Depreciation and amortization | Included expense, including any portion in COGS | Asset purchase cash or accumulated lifetime balance |
| Net revenue | Same-period revenue after relevant returns/discounts | Gross customer receipts or unrelated group sales |
Reconcile an original business example
| Line | Amount |
|---|---|
| Revenue | 1,000,000 |
| COGS | 600,000 |
| Operating expenses, including 20,000 D&A | 290,000 |
| Operating profit / EBIT in this example | 110,000 |
| Interest / income tax | 10,000 / 20,000 |
| Net income | 80,000 |
| Depreciation / amortization | 15,000 / 5,000 |
| EBITDA | 130,000 |
| EBITDA / operating / net margins | 13% / 11% / 8% |
Check the bridge: 80,000 + 10,000 + 20,000 + 15,000 + 5,000 = 130,000. The percentages are example arithmetic, not industry averages. All included D&A is counted once.
Independent negative example: net loss of 30,000 plus 5,000 interest, zero tax, 10,000 depreciation and zero amortization gives negative 15,000 EBITDA. Removing selected expenses does not necessarily turn a loss into positive earnings.
Keep Adjusted EBITDA separate and reviewable
Adjusted EBITDA = base EBITDA + signed extra adjustments. In an independent scenario, base 130,000 plus an included 12,000 proposed expense adjustment less an included 5,000 nonrecurring gain gives 137,000. This is a different example ledger from Harbor Supply.
Every adjustment needs an amount, unique description and rationale. An identical amount under a different description can still be a duplicate: the tool cannot inspect invoices or approve recurrence claims. Necessary owner work may require replacement pay; owner draws are not automatically an income-statement expense.
Read the result without calling it cash
The Harbor Supply cash bridge is 80,000 net income + 20,000 noncash D&A − 25,000 receivables increase − 10,000 inventory increase + 5,000 supplier-payable increase = 70,000 operating cash flow. This assumes a simplified US-style operating interest/tax policy, no changes in those payables and no other adjustments.
Positive EBITDA does not prove all bills can be paid. Debt principal, capital purchases, working-capital changes and actual collection dates still matter. Compare matched businesses and periods rather than applying one universal good-margin threshold.
Assumptions and limits
Use the same entity and completed reporting period. Only add back expenses already included in net income. Income-tax benefits retain their negative sign; debt principal is not interest. EBITDA is a non-GAAP earnings measure, not operating cash flow, a bank balance, a valuation or a lending decision. Adjusted items are user-proposed and not professionally approved by this tool. Revenue is optional; a missing or zero denominator has no defined margin. Money displays cents while the engine retains precision. Currency selection changes labels only; values are not converted.
Frequently asked questions
How do you calculate EBITDA?
Add included interest, income-tax expense, depreciation and amortization back to net income for the same period. Preserve negative tax benefits and avoid adding expenses already excluded.
Can EBITDA be negative?
Yes. If the earnings bridge remains below zero, the calculator reports negative EBITDA rather than forcing a positive result.
Is EBITDA the same as operating profit?
Not necessarily. EBITDA adds back depreciation and amortization, and an EBIT-based route also needs reconciliation of any non-operating items.
Why is my EBITDA margin undefined?
The margin needs a positive matched revenue denominator. Blank or zero revenue still allows the earnings total but does not produce a meaningful percentage.
Does Adjusted EBITDA approve my add-backs?
No. It applies your signed amounts separately. The records, recurrence, contract definition and professional acceptance must be reviewed independently.
Can I change currency?
Yes. Currency selection changes display labels only. Enter every amount in the same currency; no exchange-rate conversion occurs.
